A team of researchers from the Technical University of Denmark (DTU) has announced the creation of a so-called super battery made from rocks, a technology that may one day replace Lithium Ion batteries used in electric vehicle production. The team claims their discovery would lead to cleaner, safer, and longer-lasting batteries that don’t rely on rare metals or end up as toxic waste. According to the DTU team behind the battery’s creation, the key to their entry into energy storage lies in the simplicity of the materials involved. More specifically, their super battery is based on potassium and sodium silicates,...

Robert Mueller deals in chemicals for a living -- things that can unstick glue, thin paint, make plastic -- but he'd never seen an order like the one he got for sodium silicate. The compound is typically used to repel bugs or seal concrete, but this buyer's online order form betrayed a whole different intent: "To Kill Car Engines." "That worried me a little, so I picked up the phone and called the gentleman," recalls Mr. Mueller, an owner of chemical-firm CQ Concepts Inc. in suburban Chicago. What Mr. Mueller discovered is that sodium silicate is the designated agent of...
